HEAT Ne OR \IULCANIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 606,364, dated June 28,1898.

Application filed March 10, 1898.

To all whom it may concern.-

Be it known that I, GEORGE W. SLATER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Heating or VulcanizingApparatus, which improvement is fully set forth in the followingspecification and accompanying drawings.

My invention consists of an improved construction of heating orvulcanizin g apparatus which is especially applicable for vulcanizingpneumatic tires or mending otherrubber substances, the apparatus beingcheaply manufactured and the various parts thereof readily assembled. V

It further consists of novel details of construction, all as will behereinafter fully set forth, and particularly pointed out in the claims.4

Figure 1 represents a perspective view of a heating or vulcanizingapparatus embodying my invention. Fig. 2 represents a section on line a:00, Fig. 1. Fig.- 3 represents a perspective view of the lower part ofthe yoke or bail employed. I

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates a heating or vulcanizingapparatus consisting of a lower member, burner, or base B, which may beprovided with feet and has a chamber 0 within the same for the receptionof the material D, which may be asbestos, mineral wool, or othermaterial, which latter is adapted to be saturated with the heatingmedium, which may be alcohol or other ignitible fluid.

E designates a plug in engagement with the bottomof the base D for thepurpose of rendering the chamber 0 accessible or for the purpose ofenabling gas to be used as the heating medium.

F designates a cap adapted to be screwed or otherwise secured to thewick-tube F, said cap serving as a closure for the opening G when theapparatus is not in use.

H designates a flue or chimney forming the combustion-chamber,which issupported upon the base 13 and is provided with the recesses J for theadmission of oxygen and to provide the necessary draft passages for thesupport Serial No. 673,860. i (No model.)

M, the latter consisting of the yoke Q, which has at its lower portionthe lips R, which en gage the lugs S, which latter are in the presentinstanceoppositely located near the top of the combustion-chamber II.The upper portion of the yoke Q has the thumb-screw T passingtherethrough, the extremity of which is adapted to engage the member N,by means of which latter and the bed K the pneumatic tire or otherarticle N of rubber or similar material can be rigidly held while beingvul Canized, as will be hereinafter explained.

The top corners of the flue H are beveled or cut away in downwarddirection, so that the recesses or passages D exist between the chimneyand the bed K, and providing, with the recesses J ,for a draft throughsaid fine I and permitting the escape of the products of combustiontherefrom, while, however, causing said products to impinge the underside of said bed.

- It will be noticed that while the lugs M pre vent shifting ordisplacement of the bed K they serve to retard the escape of theproducts of combustion from the fine and so retain them sufficientlylong against the bed as to highly heat the latter, after which theyenter the uncovered corners of the flue's and so escape.

The operation is as follows: The tire is placed in position (seen inFig. 1) with the puncture against the bed K, and the member N is thenscrewed against the tire to the desired extent. The cap F having beenremoved and the burner ignited, itwill be seen that the heat will beapplied to the under side of the bed K, and after the tire has beenvulcanized .to the desired extent the same can be readily removed byloosening the screw P, as is evident. I

If desired, I may employ gas as the heat ing medium by removing the plugE and the material D and also the cap F, as is evident.

The upper faces of thelips R and under faces of the lugs S are curved,respectively, in reverse direction, so as to interlock, and thus preventthe shifting or displacement of the yoke or bail Qfrom the chamber orflue H.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a heating or vulcanizing apparatus, the combination of a base, aflue or combustion-chamber supported thereupon,a bed supported upon saidcombustion-chamber and a clamping device, the latter consisting of ayoke having lips for engagement with lugs on said-combustion-chamber, amember located above said bed, and a thumb-screw passing through saidyoke and en gaging said member.

2. A hollow base, a flue supported thereon, a bed mounted on said flue,a follower above the same, a screw carrying said follower and a yoke inwhich said screw is fitted, said flue having on its sidesoutwardlyturned lugs and said yoke having on its under endsinwardly-turned lips, which latter are removably engaged with said lugs.

3. Ahollow base, a flue supported thereon, a bed mounted on said flue,afollower above the same, a screw carrying said follower and a yokeinwhichsaid screw is fitted, said flue "having on its sidesoutwardly-turned lugs and said yoke having on its under endsinwardly-turned lips, which latter are removably engaged with said lugs,said bed having downwardly-projectin g lugs which enter said 9 flue.

4. In a heating and vulcanizin g apparatus, a heater, a flue, aremovable bed closing the top of said flue, a follower above said bedand a device for clamping said bed and follower to said flue, saidbedhaving lugs which enter said flue, and the corners of the latter beingcut away, forming discharge-openings,whereby the products of combustiondirected -against said bed are retarded by said lugs and dischargedthrough said corner-openings.

5. I11 a'device of the character stated, a flue Zwithoutwardly-projecting lugs on the sides' thereof, a bed supported on saidflue, a follips and lugs being reversely curved.
